More like the inside of a refrigerator, then you use a fireplace to heat up obviously which dries it up. This type of mud has more dirt than liquid in it so it won't drip down in between the logs.
Grass could also grow naturally on clay tile roof which last for centuries, if you don't wash it, birds will shit on it until grass and moss start to grow there, just like on cliffs.
It's one of those old forgotten technologies used to achieve insulation before insulation was sold as blocks of asbestos and later on just blocks of asbestos free insulation.
I cannot be a good idea to have mud over your head.
